This guide provides information for the sampling of seized-drug submissions.

The principal purpose of sampling in the context of this guide is to answer relevant questions about a population by examination of a portion of the population. For example:

By developing a sampling strategy and implementing appropriate sampling schemes, as illustrated in Fig. 1, a laboratory will minimize the total number of required analytical determinations, while ensuring that all relevant legal and scientific requirements are met.
